Or the extinction command, the LED driver chip feeds back the status information of the LED lamp to the main controller through the uplink channel.

[11] 图 1示出了本发明实施例提供的灯具控制系统的结构， 为了便于描述， 仅示出 了与本发明实施例相关的部分。 Fig. 1 shows the structure of a luminaire control system according to an embodiment of the present invention. For the convenience of description, only parts related to the embodiment of the present invention are shown.

请参照图 1， 整个灯具控制系统至少包括主控制器、 分配器 （如 Dl、 D2、 D3、 Please refer to Figure 1. The entire luminaire control system includes at least the main controller and distributor (such as Dl, D2, D3,

D4、 D5、 D6) ， 该灯具控制系统通过分配器与多个 LED灯具相连接， 以控制 LED4, D5, D6), the luminaire control system is connected to multiple LED luminaires through a distributor to control LE

D灯具， 其中 LED灯具包括 LED灯和驱动模块。 主控制器与分配器之间、 分配器 与分配器之间的数据传输均釆用以太网通信方式， 主控制器和分配器均包括具 有多个通道的以太网物理层芯片和可编程逻辑器件， 且将以太网物理层芯片的 通道设置为下行通道和上行通道两种， 其中， 主控制器通过其以太网物理层芯 片的下行通道将包含有当前操作指令和驱动参数等信息的网络数据包传输至各 个分配器中， 分配器通过可编程逻辑器件完成网络数据包的解码， 并通过以太 网物理层芯片的下行通道将当前操作指令和驱动参数传输至灯具驱动芯片中， 驱动芯片根据当前操作指令控制 LED灯点亮或熄灭； 在 LED灯具状态异常吋， 驱 动芯片通过其上行通道将检测到的异常数据信息传输至与其连接的的分配器中 ， 分配器通过可编程逻辑器件将接收到的数据打包为适于以太网传输的网络数 据包， 并通过以太网物理层芯片的上行通道将网络数据包传输至主控制器， 由 主控制器汇总所有系统信息， 生成系统状况报表， 例如当 LED出现短路或断路吋 ， 可以通过上述路径向主控制器反馈该信息， 从而更加方便査找系统的故障点 。 若只是由于驱动信号的频率偏差较大以致 LED灯具不亮吋， 可以通过上述路径 向主控制器反馈异常信息， 由主控制器重新设定控制参数， 调整驱动频率， 直 至 LED灯具点亮， 同吋多通道以太网物理层芯片的釆用也使系统数据传输速率大 大提高。D lamps, wherein the LED lamps include LED lights and drive modules. The data transmission between the main controller and the distributor and between the distributor and the distributor is performed by Ethernet communication. The main controller and the distributor both include an Ethernet physical layer chip and a programmable logic device having multiple channels. And setting the channel of the Ethernet physical layer chip to the downlink channel and the uplink channel, wherein the host controller includes the network packet including the current operation command and the driving parameter through the downlink channel of the Ethernet physical layer chip. Transmitted to each of the distributors, the distributor completes the decoding of the network data packet through the programmable logic device, and transmits the current operation instruction and the driving parameter to the lamp driving chip through the downlink channel of the Ethernet physical layer chip, and the driving chip is according to the current operation. The command control LED is turned on or off; after the LED lamp is in an abnormal state, the driver chip transmits the detected abnormal data information through its upstream channel to the distributor connected thereto, and the distributor receives the received data through the programmable logic device. Data is packaged into network packets suitable for Ethernet transmission and passed through Ethernet Up channel layer of the chip to the network data packet to the main controller by The main controller summarizes all system information and generates a system status report. For example, when the LED is short-circuited or disconnected, the information can be fed back to the main controller through the above path, which makes it easier to find the fault point of the system. If the LED lamp is not bright due to the large frequency deviation of the driving signal, the abnormal information can be fed back to the main controller through the above path, and the main controller resets the control parameter and adjusts the driving frequency until the LED lamp is lit. The use of multi-channel Ethernet physical layer chips also greatly increases the system data transfer rate.

[13] 当系统需要控制较多数量的 LED灯具吋， 还可以通过路由器将多个子系统单元 连接起来， 由主控制器统一控制， 整个灯光系统布局灵活， 如图 1所示， 主控制 器对 LED灯具的控制当前操作指令和设定的参数依次经过分配器 （D7) 、 路由 器、 分配器 （D4、 D5、 D6) 后输入至 LED灯具模块的驱动芯片， 而驱动芯片反 馈的异常信息又依次经过分配器 （D4、 D5、 D6) 、 路由器、 分配器 （D7) 输入 至主控制器， 路由器同样包括具有多个通道的以太网物理层芯片和可编程逻辑 器件， 路由器与分配器的数据传输依然釆用以太网数据通信方式。 [13] When the system needs to control a large number of LED lamps, it is also possible to connect multiple subsystem units through a router, which is controlled by the main controller. The layout of the entire lighting system is flexible. As shown in Figure 1, the main controller pair LED lamp control The current operation command and set parameters are sequentially input to the driver chip of the LED lamp module through the distributor (D7), router, distributor (D4, D5, D6), and the abnormal information fed back by the driver chip is in turn Through the distributor (D4, D5, D6), router, distributor (D7) input to the main controller, the router also includes Ethernet physical layer chip and programmable logic device with multiple channels, data transmission between router and distributor Ethernet data communication is still used.

[14] 本发明实施例中， 主控制器、 分配器、 路由器中的以太网物理层芯片为 100M 以太网物理层芯片或 1G以太网物理层芯片， 整个系统中的数据传输速度得到提 高； 且由于系统下行通道传输的数量要大于上行通道传输的数据量， 出于优化 系统资源配置的考虑， 以太网物理层芯片中推荐釆用上行通道与下行通道不对 称结构， 且下行通道数据传输速率大于上行通道数据传输速率， 例如对于 4通道 100M PHY Altima AC104-QF芯片， 可以设置下行通道 300M, 上行通道 100M。 [14] In the embodiment of the present invention, the Ethernet physical layer chip in the main controller, the distributor, and the router is a 100M Ethernet physical layer chip or a 1G Ethernet physical layer chip, and the data transmission speed in the entire system is improved; Since the number of downlink channels transmitted by the system is greater than the amount of data transmitted by the uplink channel, for the optimization of system resource configuration, the uplink physical channel chip adopts an asymmetric structure of the uplink channel and the downlink channel, and the downlink channel data transmission rate is greater than The uplink channel data transmission rate, for example, for the 4-channel 100M PHY Altima AC104-QF chip, the downstream channel 300M and the upstream channel 100M can be set.

[15] 对于大型的灯光系统， 为了改善高频信号长距离传输信号衰减的问题， 各个 LE D灯具间釆用如图 2所示的数据传输方式， 在每个 LED灯具两端分别连接有反相 器 T1和 T2, 高频信号在到达 LED灯具之间以低电平信号传输， 需要驱动 LED灯 具吋先经过反相器 T1后变为高电平， 而从 LED灯具输出的信号又经过反相器 T2 后变为低电平， 以降低在到达下一 LED灯具前的信号衰减。 [15] For large-scale lighting systems, in order to improve the attenuation of long-distance transmission signals of high-frequency signals, the data transmission methods shown in Figure 2 are used between the various LE D lamps, and the opposite ends are connected at each of the LED lamps. Phase devices T1 and T2, the high-frequency signal is transmitted between the LED lamps with a low-level signal, and the LED lamps need to be driven to go to the high level after passing through the inverter T1, and the signal output from the LED lamps is reversed. Phaser T2 goes low to reduce signal attenuation before reaching the next LED fixture.

[16] 本发明中， 灯光系统选用处理能力强、 速度快的主控制器为核心对 LED灯具进 行实吋监控管理， 整个灯光系统数据传输速率大大提高， 不仅可以支持 flash节目 制作方式， 还可以通过执行软件达到支持参数化自动产生、 屏幕截取等节目制 作方式的目的。 [17] 综上所述， 本发明实施例提供的灯具控制系统中， 主控制器、 分配器以及路由 器均包括具有多个通道的 100M或 1G以太网物理层芯片和可编程逻辑器件， 实现 了灯具状态的检测， 便于査找系统的故障点， 很大程度简化了系统的管理和维 修， 系统数据传输速度也得到提高， 而且不对称的上行通道、 下行通道数据传 输方式的釆用使系统具有了自动频率调整的优点； LED灯具之间反相器的釆用降 低了高频信号的衰减， 使每个分配器带负载数量大大增加， 一定程度上降低了 现场布线难度， 而且拥有快速的数据传输、 处理功能强大的主控制器的灯具控 制系统支持多种节目制作方式， 使节目内容更加丰富多彩。[16] In the invention, the lighting system selects the main controller with strong processing capability and fast speed as the core to carry out the actual monitoring and management of the LED lamps, and the data transmission rate of the whole lighting system is greatly improved, which can not only support the flash program production mode, but also Through the implementation of the software, the purpose of supporting the automatic generation of parameters, screen capture and other program production methods is achieved. [17] In summary, in the luminaire control system provided by the embodiment of the present invention, the main controller, the distributor, and the router each include a 100M or 1G Ethernet physical layer chip and a programmable logic device having multiple channels, and The detection of the state of the lamp makes it easy to find the fault point of the system, which greatly simplifies the management and maintenance of the system, and the system data transmission speed is also improved. Moreover, the use of the asymmetric uplink channel and the downlink channel data transmission method makes the system have Advantages of automatic frequency adjustment; The use of inverters between LED lamps reduces the attenuation of high-frequency signals, greatly increasing the load per distributor, reducing the difficulty of field wiring to a certain extent, and having fast data transmission. The luminaire control system that handles the powerful main controller supports a variety of program production methods to make the program content more colorful.
